Most standard household fireproof safes carry a UL-72 Class 350 rating. This means they are built to keep internal temperatures from exceeding 350° F during external fires of up to 1850° F for their stated hourly rating. While this is considered adequate protection for paper documents and other less sensitive materials, it could put your card collection at risk if stored in PSA, BGS, CGC, or other graded card slabs. Common slab plastics such as Acrylic and Polymethyl Methacrylate begin to soften at temperatures around 160 to 200° F and melt around 320° F.
Turtlecase.com's Phoenix DataCare and DataCommander series are extra insulated and designed to protect sensitive magnetic media on hard drives or tapes. Unlike other safes, they carry a more robust UL-72 Class 125 rating, meaning internal temperatures will not exceed 125° F in the event of an external fire for 1 to 2 hours depending on model. This 225 degree difference is more than enough to keep plastic slabs intact and protect the precious collectibles held within.
With the proliferation of wildfires and other natural disasters, there's no time like the present to ensure your collection's integrity. Shop the DataCare and DataCommander series today
